I have a website that contains several aspx pages linked to a single aspx.vb code behind file. Four of these aspx pages have a single button on each (four total). My issue is handling each button's click event on each page using the single code behind file.
My four buttons' names are:
[code]....
have a data access layer, a business logic layer and a presentation layer (ie. the pages themselves). handle the OnPreInit event and populate collections required for the page. All the data comes from an SQL server database and I do not use caching.I handle a button click event to grab values from a form and insert a new object into the database. The problem is that by the time I handle the click event, the collections have already been populated, so the new item which has been inserted into the database has not been retrieved.What is the accepted solution to this?I could insert the new object directly into the collection and re-bind the GridView, but the SQL query selects only a set of objects and the new object could fall outside of this set.

How to check all asp.net checkboxes on single asp.net button click event

I want to F11 through a button click event but the breakpoint I have set inside it doesn't halt code execution. I can see the shortest of pauses on the breakpoint itself but the code only stops executing at the next breakpoint outside the event (which is the page load ie. a postback). Why can't I step through the code in the button click event?

When I click on Home,I am getting Javascript error Button1_Click is undefined,but it is defined in the code behind,you can see above.
i have written an button click event in js file but the event wasnt fired the code seems below
$("#btnSearch").click(function () {
debugger; alert("search button event fired");
$("#ctl00_MaintenanceContentHolder_btnSearch").click(function
ugger; alert("searchbutton event fired");
I just had a few questions about a basic version of the Singleton Method that is posted below. I've just created a very basic class that implements the Singleton Method. Afterwards, I create the first instance in the Page_Load and then when I push a button on the Web Page, I create a reference to the Singleton Class and then print out the "SingletonName" property to ensure that it has a value.
Code:
public sealed class Singleton
{
private static readonly Singleton instance = new Singleton();
[code]....
1) If 2 or more users are concurrently running this application, will the users have a new Singleton Object, or will the user be given the Objects that the first user created? In other words, is this Global to the application or just the session? I believe it is global for each session and not to the application but I wanted to make sure.
2) In the button click event, should you create a new reference, like I am doing, or should I do something like "Response.Write(Singleton.Instance.SingletonName)"?
I'm building a button in my code behind file and want to bind the click function to an existing click function of a different button. How do I handle this? I was hoping for something simple like:
Button b = new Button();
b.onClick = otherClickEvent();
but apparently that's not doable. Am I missing something here. I'm aware of OnClientClick, but that only deals with the JS side of things apparently.
i have an form with an button and some input controls. some time due to input problem i may get error after that if i refreshed the page then that time the button click event has fired, how to avoid this kind of bad event fire.
View 3 RepliesSituation:
1) Click on 'Check' button and the button will disable
2) Run a processing code(for checking) and once it is done, navigate to a new page(NewPage2).
Here are 2 code situations (1):
[Code]....
and if I do this way (2),:
[Code]....
it will navigate to NewPage2.aspx, but during the execution of the processing code, ButtonCheck control will not be disabled as the Click Event has not finished, and I want it to disable during the checking process. If the 1st option is executed, it will throw to me "Response is not available in this context."? HttpContext is null for (1). In my opinion, I think that the navigation does not recognise the response object as it is in a thread and has exited out of the buttoncheck event. But I'm still not sure why.
how to disable the button and run processing code during the click event and be able to navigate to a new page?

In my ASP.Net Web Site I have a button.When I click the button and then reload the page via browser,the click event of the button fires.
View 4 RepliesI will describe my problem in simple way so it's not exactly what I'm trying to do but the idea is the same.Here is the problem:
I create dynamic buttons from code behind.I get some id from query string,create button with that id ,dynamic add event handler to click event,and add button to placeholder.I store the list of id-s in session and in page load method recreate these buttons and add to placeholder.One of the id-s is CurrentId and it's also stored in session.Buttons click handler do something like this
Button b=(Button)sender; Session["CurrentId"]=Convert.ToInt32(b.ID);
In page load when I create buttons I want to set button text property different from others if id==Convert.ToInt32(Session["CurrentId"]) when list of id-s are gotten from session.But problem is that click event handler is called after page load,and when I create buttons in page load ,CurrentId in session hasn't been channged by click event handler.Can you suggest any solution to this situation?
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
if (!IsPostBack) // If page loads for first time
Session["update"] = Server.UrlEncode(System.DateTime.Now.ToString()); // Assign the Session["update"] with unique value

I just discover why some validation is working bad on some of my forms: the button click event is being called before page load.
What I need for good is (I consider this is a normal cycle of events):
The user press a buttonSome validation occurs at client side (js function returns true if success)Some validation occurs at server sideThe page loads again showing the results
But this is what I get (BAD):
The user press a buttonSome validation occurs at client side (js function returns true if success)The page loads showing no results, because server validation hasnt happened yet Some validation occurs at server sideThe page doesn´t loads again and I cant see the results, so my client cant know what happened on the server side
This is how I tried to implement this:

In the logout link button click event I have cleared the session variables.I am checking these session variables for null values at each page's load event.If it has the null value redirecting them to the login page.But the problem is whenever I click the browser back button,the page_load event won't get called.For that I have cleared the the browser cache history.
